Still 11 days, and you get your 3.9hrs for sitting standby... You don't get the full 8 unfortunately.

Reserve can work for or against you depending on how lucky you are. Since ive been at Eagle I have mostly been on the FOR side of things. I did get junior manned twice in one day (going into New years day, and then Jan 2nd) which sucked, but I was expecting NY Day at the least. More times than not (especially with staffing lately) when you finish a trip on your last day, there isnt anything else for them to tack on to you and you get to go home (at least for FOs). It definitely helps a LOT to be more senior as you can proffer for trips when you want (for commuters like myself, this is a great thing), or sit RAP if there isnt much in open time and possibly sit at home (depending on where you live).

It is NOT all misery and abuse (unless you are a captain right now ). You will be likely to sit around more than fly. In all the months I worked reserve I think the most I flew was 55hours, and that was actively trying to get trips/overnights every day I worked. It all just depends on how many people are above you and if there are any good trips in open time.
